APIs
importOrder
type: Array<string>
A collection of Regular expressions in string format.
"importOrder": ["^@core/(.*)$", "^@server/(.*)$", "^@ui/(.*)$", "^[./]"],
Default behavior: The plugin moves the third party imports to the top which are not part of the importOrder
list.
To move the third party imports at desired place, you can use <THIRD_PARTY_MODULES>
to assign third party imports to the appropriate position:
"importOrder": ["^@core/(.*)$", "<THIRD_PARTY_MODULES>", "^@server/(.*)$", "^@ui/(.*)$", "^[./]"],
importOrderSeparation
type: boolean
default value: false
A boolean value to enable or disable the new line separation
between sorted import declarations group. The separation takes place according to the importOrder
.
"importOrderSeparation": true,
importOrderSortSpecifiers
type: boolean
default value: false
A boolean value to enable or disable sorting of the specifiers in an import declarations.
importOrderCaseInsensitive
type: boolean
default value: false
A boolean value to enable case-insensitivity in the sorting algorithm
used to order imports within each match group.
For example, when false (or not specified):
import ExampleView from './ExampleView';
import ExamplesList from './ExamplesList';
compared with "importOrderCaseInsensitive": true
:
import ExamplesList from './ExamplesList';
import ExampleView from './ExampleView';
importOrderParserPlugins
type: Array<string>
default value: ["typescript", "jsx"]
Previously known as experimentalBabelParserPluginsList
.
A collection of plugins for babel parser. The plugin passes this list to babel parser, so it can understand the syntaxes
used in the file being formatted. The plugin uses prettier itself to figure out the parser it needs to use but if that fails,
you can use this field to enforce the usage of the plugins' babel parser needs.
To pass the plugins to babel parser:
"importOrderParserPlugins" : ["classProperties", "decorators-legacy"]
To pass the options to the babel parser plugins: Since prettier options are limited to string, you can pass plugins
with options as a JSON string of the plugin array:
"[\"plugin-name\", { \"pluginOption\": true }]"
.
"importOrderParserPlugins" : ["classProperties", "[\"decorators\", { \"decoratorsBeforeExport\": true }]"]
To disable default plugins for babel parser, pass an empty array:
importOrderParserPlugins: []
How does import sort work ?
The plugin extracts the imports which are defined in importOrder
. These imports are considered as local imports.
The imports which are not part of the importOrder
is considered as third party imports.
After, the plugin sorts the local imports and third party imports using natural sort algorithm.
In the end, the plugin returns final imports with third party imports on top and local imports at the end.
The third party imports position (it's top by default) can be overridden using the <THIRD_PARTY_MODULES>
special word in the importOrder
.
